CORNER-SHIELD AND RETAINING MEANS THEREFOR.

No. 799, 13 I).

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed June 14, 1905. Serial No. 265,120.

To all whom it may concern.-

Be it known that I, OHARLEs H. ANDERSON, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvementsin Corner-Shields and RetainingMeans Therefor, of which the following is a specification.

My invention relates to improvements in corner-shields and retainingmeans therefor in buildings finished in marble, stone, iron, tiling, andthe like.

The objects of my improvement are, first, to provide a corner-shield ofsuitable material adapted to be fastened and retained in position by theuse of plastic material that will harden when set; second, to provide acornershield molded or formed of glass in any color or tint and inimitation of marble, stone, iron, tiling, or other finishing material,and, third, to provide acorner-shield of practical utility, permanentlyserviceable and of low initial cost to manufacture, for the purpose ofpreventing the accumulation of dust and dirt and lessen the laborrequired to keep the corners clean.

With the above and other objects in view this invention consists of thenovel form and the means for setting and retaining the same and thecombination and arrangement of parts hereinafter more specificallydescribed, illustrated in the accompanying drawings, and particularlypointed out in the claims hereunto appended.

In describing the invention in detail reference 15 had to theaccompanying drawings, forming a part of this specification, whereinlike numerals of reference indicate corre sponding parts throughout theseveral views, and in which Figure 1 is a perspective view of mycorner-shield located in a corner. Fig. 2 is a horizontal sectional viewon line 2 2 of Fig. 1 looking in the direction of the arrows. Fig. 3 isa side view of the corner-shield. Fig. 4 is a rear view of thecorner-shield. Fig. 5 is a modified form of the corner-shield.

Referring to the drawings by reference-numerals, 1 denotes the body ofthe cornershield, which preferably consists of a solid piece of glasssubstantially triangular in outline, having a rear cut-away portion orfiat surface 2, lateral faces 3 3 3, lateral depressions or grooves 4 44, and a curvilinear or concave front surface 5. The lateral depressionsor grooves 4 4 4 are preferably made wider or deeper at their outerends-that is to say, their ends nearest the front surface 5 of theshield 1-for the purpose of affording more of an anchor-when theplaster-of-paris or cement is forced into'said depressions and set orhardened.

Other forms of depressions, grooves, or channels may be made than thosedisclosed in the drawings.

The cut-away or flat rear portion 2 of the shield 1 obviates thenecessity for much cleaning of corners before setting the shield, and,further, it provides a space for a body of retaining material 6 betweenthe corner of the building and the rear of shield 1. The material inplastic condition that is forced into the depressions or grooves 4 4 4continues integral with the body of such material positioned betweentheshield 1 and the corner in which the shield is installed.

-Reference character 6 denotes the setting material or retaining meanswhen the shield is in normal position.

It is found in practice that the setting material while in a plasticstate will to a sufficient extent be forced between the ends of thefinishing material and the floor of the corner of the building topermanently anchor the shield.

In practice ithas been found that plaster-ofparis sets rapidly, and atthe instant of setting it expands or increases in bulk, so that theshield will be held more firmly as the retaining material sets orhardens.

The shield 1 is preferably molded of glass and may be stained or coloredin imitation of the particular material with which the building may befinished.

In practice if plaster-of-paris is used it should be diluted with waterinto a paste and a suflicient quantity put into the corner when theshield is to be set. The shield 1 will then be placed in the corner withforce enough to fill the lateral depressions or grooves 4 4 4 and tosqueeze out any surplus plasterof-paris. The surplus, if any, will thenbe wiped away before it sets or hardens.

as well as the form of depressions shown in Figs. 3 and 4, thedepressions communicate with or open into the space at the rear of theshield and between it and the corner of the IIO building. In otherwords, reference characters 4 4. 4 denote depressions-0r groovescoextensive with the rear fiat surface of the shield 1 and extend aportion of the distance across each of the three lateral faces.

It will be apparent that minor changes in the details of constructionmay be made without departing from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. A corner-shield consisting'of solid glass, triangular in outline andprovided with a plurality of lateral depressions communicating with therear surface of said shield, substantially as shown and described.

2. A corner-shield of solid glass, triangular in outline and havingthree lateral surfaces each carrying a groove which communicates withthe rear surface of said shield, substantially as shown and described.

3. A corner-shield, triangular in outline, and having five faces orsurfaces, each of the three lateral surfaces thereof carrying a groovewhich communicates with therear surface of said shield, substantially asshown and described.

4:. A corner-shield consisting of a solid substance, triangular inoutline, and provided with a plurality of lateral depressions communicating with the rear surface of said shield, in combination with aplaster-of-paris or cement setting, substantially as shown anddescribed.

5. A corner-shield of glass, triangular in outline, and provided with aplurality of lateral grooves communicating with the rear surface of saidshield in combination with a plaster-of-paris setting, substantially asshown and described.

6. A corner-shield comprising a solid, triangular in outline, havingfive surfaces, each of the three lateral surfaces thereof provided witha depression, in combination with a plaster-of-paris retainer,substantially as and for the purposes set forth.

7. A corner-shield consisting of a triangular solid of stained glasshaving three lateral surfaces each provided with a groove opening in therear face of said shield, in combination with a plaster-of-paris orcement retainer, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
